TAMPER-INDICATING CLOSURE AND METHOD OF MANUFACTURE |
摘要 |
A tamper-indicating closure of integrally molded plastic construction that includes a base wall having a peripheral skirt with an internal thread for affixing the closure to the container finish. A tamper-indicating band is connected to an edge of the skirt by frangible bridges. A stop flange extends from an edge of the band remote from the skirt for abutment with a bead on the container finish to inhibit removal of the closure absent fracture of the frangible means. A plurality of circumferentially spaced openings extend radially through the skirt at a position between the frangible bridges and the internal thread. These openings provide for ingress of cleansing solution during a washing operation after the closure is applied to a container to flush any residue from between the tamper-indicating band and the closure finish. Drain openings are provided in the stop flange and/or the tamper-indicating band to allow drainage of the flushing solution, and also to allow drainage of any accumulated liquid in wet-finish applications.
